What is the Haze Xtreme strain?
Haze Xtreme is a mostly sativa hybrid from Crop King Seeds, made by crossing Original Haze with Cheese to push Haze's trippy, cerebral high further. SeedFinder notes it has never been offered as feminized seed, so it is grown from regular seeds that produce both males and females. Listings put flowering at 8 to 10 weeks (about 63 days), THC between 15% and 22% depending on the source, and the aroma at spicy herbs, earth and a creamy cheese note.
Ratio from AllBud; Crop King lists it only as sativa-dominant.
SeedFinder records that Haze Xtreme was never released as feminized seed.
Haze Xtreme strain specs
Haze Xtreme is a little-documented strain, so these figures come from three places: Crop King Seeds' listing, SeedFinder's entry for the Crop King line and AllBud's profile. The sources disagree on THC and CBD, and the rows show both.

Where does the Haze Xtreme strain come from?
Haze Xtreme was bred by Crop King Seeds by crossing Original Haze with Cheese. The breeder's description, quoted on SeedFinder, says the aim was to take Haze and make it "Xtreme", with a stronger psychedelic edge and a potent sativa high. Original Haze is the long-flowering California sativa of the 1970s, while Cheese is the famously pungent Skunk-family cut from the UK that adds body, faster finishing and its savory smell.
Beyond that, Haze Xtreme's history is thin: SeedFinder has no family tree, phenotype notes or grow reports for it, and no independent lab data has been published. What sources do agree on is the Haze × Cheese pairing, a mostly sativa profile and the fact that it has only ever been sold as regular seed.
What should you know about growing Haze Xtreme from regular seeds?
Regular Haze Xtreme seeds grow both male and female plants, roughly half and half, so you sex them in early flower and remove the males unless you want to breed. Haze-type males often show their sex a few days later than indica-heavy strains, so check the nodes every day in the first two weeks of 12/12. A good male carries the spicy Haze-Cheese mix into new crosses, which is the main reason breeders seek out regular seeds of a line like this.
Expect variety between females. With a Haze and a Cheese parent, some Haze Xtreme plants lean tall and airy, others shorter and denser, so growing several lets you choose a keeper.

- Sociable
- Uplifted
Haze Xtreme's intense head high can feel racy or scattered at higher doses, and dry mouth is common.

How do you grow Haze Xtreme seeds?
Haze Xtreme seeds need moderate skill: sprout extra regular seeds, train the stretchy plants early, remove males as soon as they show, and keep temperature and humidity steady through 8 to 10 weeks of bloom.
- GerminateAbout 1 week
Haze Xtreme customer reviews mention good soil and careful watering; keep seedlings damp, never soaked.
- Vegetate4–6 weeks indoors
Top Haze Xtreme early and train with LST; its Haze side stretches, so a short veg suits small tents.
- Flower8–10 weeks
Sex the plants in the first two weeks of 12/12, pull males, then keep air moving as the buds form.
- HarvestDay ~63–70 indoors · October outdoors
Harvest when trichomes are mostly cloudy for the clearest, most energetic Haze Xtreme effect.
Grow tips for Haze Xtreme
- Identify males early. Look for small, ball-shaped pollen sacs at the Haze Xtreme nodes; females show wispy white pistils. Remove males before the sacs split.
- Keep the climate steady. Crop King notes Haze Xtreme is sensitive to temperature swings and humidity, so aim for 20–28 °C (68–82 °F) and good ventilation.
- Don't overwater. Growers report Haze Xtreme does best in well-draining soil with a dry-back between waterings.
- Plan for height. Listings give Haze Xtreme 1.5–2.4 m, and outdoor plants can go well beyond, so top early or use a SCROG net.
- Store pollen if you breed. Collect pollen from a chosen Haze Xtreme male in a separate room, dry it and keep it sealed and cold until use.

Think twice if you
- Want guaranteed female plants (Haze Xtreme was never sold feminized)
